Serial nogizsaz'rez e This invention relates to. improvements in paper handling, machines, and has. reference particularly to means, for diverting two or more different, sheetsv .orsignatures following each other through a told-Zing machine. or-

other paper handling machine; into two or more different courses where: they may be collected separately.

Sheet cilefiectormech anisrn for the purpose stated has been suggestedheretofore but. in i such mechanism, so far as I am aware, the defiector has oscillated back and. forth between its different operativepositions. In the pres.- ent intention the deflector turns always inthe same direction and is preferably power driven through a friction clutch which slips when everthe deflector ismotionless, and becomes effective, to turn the deflector whenever a stop mechanisinthat' is providedin the. machine is 1 ith-d-rawnby means-which are actuated hy the travel of the sheets themselves. Thefdes flecter operating mechanism therefore is not synchronized with they other moving parts of the v machine, but is operated in properly timed relation with the travel of the'sh'eets, being motionless when thetravel of thesheets. is interrupted for any reason. 7 One oztthe obflect-s ofthe provision of a powerimeansfor turning the deflector, so that the, load imposed upon the folded sheets is only sufiicient totripa stop mechanisinf This. is of some srinipdrtance. wh ere light weight inaterial isto be, handled. Another object is the provision of simple and" efiective stop mechanism, preferably engaging the deflector directly, to. hold the same in any one of a plurality of operative positions.

Other objects and features of novelty will appear as I; proceed with a description of that embodiment of the invention which, for the purposes of the presentv application, I have illustrated in the accompanying drawings, in which: r Q

, In the drawingsl have shownat 10, a frag Yinent. at, the deliveryend of, aiolding'machine or the like, comprising sheet' forwarding meanslconsi'stinn ofrolls 11 and 12, which carry inte'rr'neshing gears: 13 and 14- respee npclosely adiacent. to the delivery end of. the

folding, machineQas, indicated in Eig's, 1, endfi, and is preferably detachably secured thereto, The frame 15 carries; a guidep'late 16 which is positioned to receive'the sheets i delivered from the sheetforwardingmeans 18.. The latter rolls have' intermeshing gears 19, 20, which ma and, preferably do derive 11,,12-and to direct them into feed'rolls 17,,

their power from the folding machine, as through an idler-21, the-gears 19, 2'0 turning I V at the same speed a'sthe gears 13., 14, so that the two pairs of feed rolls to which they are connected shall turn at the same rate of speed.

On the rear side of the .machine the roll 17 carries a gear "22 which rneshes with an idler 23, the idler in turnflrneshing with a gear which is mounted on shaft'2 5that extends across the machine and carries paper feeding wheels 26. Below the shaft 25 there are two feed rolls 28, 29 of metal or other non resilient material that are driven through gears 30, 31 (Fig. 1). The gear 31 in turn meshes with a gear 32 on shaft 33 which carries paper feeding wheels 34 similar to the wheels 26 on the shaft 25. As indicated in Figs. 5 and 6, sheets may travel either between the roll 28 and the wheels 26 or between the roll 29 and the wheels 34, that is to say, either in an upper course or in a lower course. Those sheets which take the upper course are deposited upon a suitable collecting means, as for instance a stacker belt 35, while those taking the lower course may be deposited upon a stacker belt 36. These belts may be driven by any suitable means, as for instance by a series of gears 37, 38, 39 at the back of the machine the gear 37 being driven from gear 30 through a reduction gearing consisting of a pair of idlers 9 and 99 secured together, idler 9 meshing with gear 30 and idler 99 meshing with gear 37.

A paper deflector 41 is mounted in the frame on the rear side of the feed rolls 17 18, being rotatable upon a trunnion 42 at its rear end and at its forward end being pinned to a stub shaft 43 which extends through a bearing in the frame 15, as well shown inFig. 3. A gear 44 is loosely mounted upon the shaft 43 and is driven continuously in a clockwise direction, as viewed in Fig. 1, by a gear 40 on the forward end of roll 29. Clutch blocks 45, 46, lined with friction material engage the shaft 43 adjacent the gear 44, being resiliently clamped upon the shaft by bolts 47 acting through coil springs 48. One of the blocks 45, 46 is pinned to the hub of gear 44, so thatthese blocks move with the gear at all times. Hence there is a tendency for the shaft 43 to turn with the clutch blocks 45, 46 in a clockwise direction, but when its rotation is interefered with the clutch blocks turn upon the shaft. j 7

Referring now to the stop mechanism, in connection with shafts 25-and 33 I employ pivoted shoes 49 and 50 respectively, which are mounted upon the inner ends of short rock shafts 51 and 52, the outer ends of which extend through bearings in the forward wall of the machine. These shoes should just clear the rolls 28 and 29, so that when a sheet passes between oneof these rollsand the adjacent shoe, the shoe will be swung to rotate the shaft 51 or 52 as the case may be. Obviously it is necessary to adjust the distance between the shoes and the rolls 28, 29 in order to enable them to function properly for different weights of paper and different numbers of folds in the sheets handled, and to this end the inner bearings for the shafts 51, 52 are mounted in levers 53, 54, which are pivotally mounted intermediate their endsupon pins 55 and 56 that are threaded into brackets 57 and 58 which are bolted to the frame. The ends of the levers 53 and 54 remote from the shaft bearings are adjustable by means of screws 59 and 60 which may be held in adjusted position by lock nuts 61 and 62 respectively, the levers being held against the ends of the screws by coil springs 63, 64 which have bearing upon thelevers and upon fixed abutments in the brackets 57 and 58.

Inasmuch as the adjustment just described moves the inner bearings of the shafts 51 and 52 while the outer bearings thereof are fixed within the frame of the machine, I form each of these shaftswith curved surfaces, as illustrated in 2, where the shafts engage their bearings. The shoes 49, 50, their adjustable mounting, and the details of the shafts 51, 52 form no part of my invention, except in combination with certain other parts of the machine herein described.

On the outer ends of the shafts 51 and 52, outside the frame of the machine, there are short cranks 65 and 66 connected by links 67 and 68 with cranks 69 and 7 O which are fixed to shafts 71 and 72, the latter being oscillatably mounted in and extending through the frame 15. The shaft 71 on its inner end carries a finger 73 with a hook on the free extremity thereof. The shaft 72 on its inner end carries a similar finger 74 which, however,. has a plain extremity. The hooked end of the finger 7 3 forms a stop to hold the deflec tor 41 in the position illustrated in Fig. 5, while the free extremity of finger 74 constitutes a stop to hold the deflector in the position of Fig. 6. In order to urge the fingers 73 and 74 to their operative positions, shown in full lines in Figs. 5 and 6, and also in or der to urge the shoes 49 and 50 toward the left in those figures, I attach to the outer end of crank 65 and to a lug on link 68, tension springs 75 and 76 respectively, which at their outer ends are connected with screws 77 and 78 threaded through pins 79 and 80 fixed in the frame of the machine. By this means the tension of the springs 75, 76 may be regulated.

Operation: Assuming that folded sheets or signature of two different kinds are following each other in regular sequence through a folding machine or the like having sheet forwarding means 11, 12, and that as the first sheet travels into the machine and through the feeding rolls 17, 18 the deflector 41 is in the position of Fig. 5, this sheet willbe divided by the deflector upwardly between roll 28 and the wheels 26 of shaft 25. After the forward edge of the sheet in passing over the roll 28 strikes the shoe 49, the latter is swung to the dotted line position of Fig. 5, and this movement of the shoe is transmitted through its shaft 51, the crank 65 thereon, the link 67, crank 69, and shaft 71 to stop finger 73, throwing the latter to the dotted line position of that figure.

Immediately the rotating friction 'cl'ntch blocks 45, 46 grip the shaft 43 and turn the same clockwise, whereby the deflector is swung through something lessjthan' a right angleto thepositionof Fig. 6, where its movement is interrnpted'by the stop finger 74. This operation may, and frequently" does, occur before the rear edge of the sheet has passed entirely over the" deflector, but the movement of the, deflector before the travel of the rear edge of the sheet thereover does no harm since the sheet is firmly gripped. by roll 28' and wheels 26. Furthermore the deflector is always in position to properly direct the next succeeding sheet, no matter how closely it follows.

The next succeeding sheet now strikes the under side of the deflector 41 and is directed downwardly between the roll 29 and the wheels 34 on shaft 33, whereupon the sh'oe750 is swung to dotted line position and operates through shaft 52, crank 66, link 68, crank 7 O, and shaft 72 to throw stop finger 74 to the dotted'line position of Fig. 6, thereby releasing deflector ,41. The friction clutch again takes effect and turns shaft 43, this time through an angle somewhat greater than ninety degrees, to a position one hundred and eightydegrees from the first position of Fig.

5, where its motion is interruptedby the hook ber of courses also is not necessarily limited,

. to two, although a machine having two courses is illustrated herein for the sake of simplicity in the disclosure of the invention. Still other changes from the disclosed structure are possible without departing from the spirit of the invention, and I therefore desire it to be understood that the invention is not to be construed as limited by any of the details included in the drawings or specification.
